WAVE-MOTOR.

Specification of Letters Patent. Patented Sept. 26, 1911.

Application filed March 9, 1911. Serial No. 613,280.

the floating buoy type and the objects are,

first, to provide a mechanismthat is simple of construction, durable andeasily installed, second, to provide a means of transmitting power fromthe movement of the waves, third,to provide a simple means of engagin gand disengaging the power shafts which operate in connection with thewave propelling mechanism.

ith these and other objects in view, as willappear, my inventionconsists of certain novel features of construction, combination andarrangement of parts as will he hereinafter described in detail andparticularly set forth in the appended claims, reference being had tovthe accompanying drawings and to the characters of reference thereon,which form a part of this specification,

- in which down.

Figure 1 is a side elevational view of one unit of my mechanism shown inconnection with a wharf to which it is connected, Fig. 2 is a top orplan view thereof showing parts of the wharf broken away, Fig. 3 is anelevational view at right angles to that of Fig. 1, Fig. 4 is asectional view in detail of a ratchet pulley in connection with aportion of a shaft, and Fig. 5 is a transverse sectional view thereof.

Similar characters of reference refer to similar arts throughout theseveral views.

The oat 1, vertical rack 2, loose gear 3, loose gear 4:, ratchet wheel5, ratchet wheel 6, gear 7, gear 8, intermediate. gear 9, shaft 10,shaft 11, shaft 12, pulley 13, pulley 14, shaft 15, pulley 16 and flywheel 19 constitute the principal parts of my invention. The float 1 iscylindrically shaped, and tapered toward each end and is preferabl madeof a log, but may be of any material, and hollow, the principal objectbeing to get a float of just sufficient weight to float nicely in thewater. Set in the lower surface of this float is a weight 1 for thepurpose of keeping that portion of the float In each end of thefloat isprovided a shaft 1 upon which is revolubly mounted parts,

a roller 1 which is retained in its positions on said shaft by means ofnut 1*. These rollers are adapted to roll between two vertical piles 17,which are spaced apart, thus providing a way. Encircling the float 1 isa band 2 which connects at its top side with a two faced gear rack 2 bymeans of bolts 2". This gear raclc extends vertically through the floorof a wharf 18 and is provided with a vertical slot 2. The rack 9. isadapted to reciprocate vertically on a guide 18? on the wharf. On eachside of rack 2 and engaging with the rack teeth thereon are gears 3 and4 which are loosely mounted on shafts 10 and 11, and said shafts aresubstantially mounted on the wharf 18 by means of boxes 18". Upon thesaid shafts l0 and 11 are rigidly mounted gears 7 and 8, and betweengears 3 and 7 on shaft 10 and between gears l and 8 on shaft 11 arerigidly mounted ratchet wheels 5 and (5. These ratchet wheels 5 and (5are adapted to engage with spring bolts 3 and 4 which are mounted ongears 3 and 1 and adapted to engage with the teeth on ratchet wheels 5and (3 when in the position as shown in Fig. 1. Between the rigidlymounted gears? and 8 and en gaging with the inner sides of said gears isintermediate gear 9 which is rigidly mounted upon shaft 19.. On shaft 12is mounted tight pulley 13 which connects with a loose pulley 14 and aratchet pulley 16 by means of a belt 14 mounted on a shaft 15 which isrevolubly mounted on the wharf 18. also mounted fly wheel 19 which isforthe purpose of retaining the momentum of said shaft. As shown best inFigs. 4 and 5 the shaft 15 is provided near the center of the pulley 16mounted thereon, with ratchet teeth 15. Centrally located in saidpulley, and adapted to engage with said ratchet teeth is a pin 16 in ahole in said pulley, in connection with a compression spring 16". Thisis for the purpose of allowing the shaft to, revolve in the pulley at agreater speed than the pulley and in case the shaft is not revolvingfaster than the pulley, the pulley. will carry the shaft with it at itsfull speed. This shaft maybe connected to any mechanism it is desired todrive, preferably an an.- compressor. A

Though I have shown and described a particular construction andarrangement of I do not wish to be limited to this particularconstruction and arrangement.

On shaft 15 is.

said shafts, a vertical way for each of said but desire LQ include inthe purview of my invention, particularly the construction andarrangement substantially as claimed. 'I have shown only oneunit, buttheremay be a plurality,all connected to one "drivenshaft.

It will be obvious that with the mechanism as constructed each verticalimpulse of the wave will raise or lower the float 1, between the piles17, earryingwith it gear rack 2 which will revolve gears 3 and 4 whichare connected to the ratchets 5 and 6 which in turn will cause the wheel7 to revolve when the float is rising and the wheel 8 to revolve whenthe float is lowering as the teeth on the ratchets 5 and 6 are inopposite directions to each other. This will revolve shaft 12 through anintermediate gear 9 Which in turn will revolve shaft 15, which may beconnected to any driven mechanism.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A wave motor comprising a float, aplurality of shafts mounted thereon, a roller mounted on each of saidshafts, a way and a loose adapted for each of said rollers, a doublerack mounted on said float, "ears in connection with said rack andratchet wheels in connection with said gears, all substantially as setforth. 2. A wave motor comprising a cylindrically shaped float, a shaftmounted oneach end thereof, a roller mounted on each of said shafts, avertical way for each of said rollers, a double rack mounted on saidfloat, gears in connection with said rack and ratchet wheels inconnection with said gears, all substantially as set forth.

3. A wave motor comprising a cylindrically shaped float, a shaft mountedon each end thereof, a roller mounted on each of rollers, double gearand rack means for transmitting power to a shaft, and ratchet wheels inconnectionwith saidgcars, all substantially as set forth.

4. A wave motor c ')1n )rising a cylindrically shaped Heat, a shaftmounted on each end thereof, a. roller mounted on each of] said shafts,vertical ways for each of said rollers, a gear rack, loose gears inengagement with said gear rack, ratchet wheels in [engagement with saidloose gears, other shafts carry-- gears rigidly mounted onthe ing saidratchet wheels, an intermediate gear in connection with ed gears and amomentum retainer in connection therewith, all substantially as. set

forth.

5. A wave motor comprising a cylindrically shaped float, means forretaining it in a certain lateral position, a two faced vertical rackadapted to reciprocate vertically therewith, loose gears in connectionwith said rack, ratch'ets in connection with said loose gears, rigidlymounted gears in' connection with said ratchets,an intermediate gear inconnection with said rigidly mounted gears, a pulley provided! with aratchet in connection with said intermediate gear, pulley adjacent tosaid pulley mounted upon the same shaft, all substantially as set forth.

6. A wave motor comprising a cylindrically shaped float, means forretaining it in a certain lateral position, a two faced vertical rackadapted to reciprocate vertically therewith, loose gears in connectionwith said rack, ratchets in connection'with said loose gears, rigidlymounted gears in connection with an intermediate gear, a tight pulley inconnection with said intermediate gear, a loose pulley in connectionwith said other pulley mounted upon another shaft, a

pulley mounted on said other shaft provided with means for allowing theshaft to revolve faster than the pulley and to prevent the pulley. fromrevolving faster than the shaft, and a fly wheel mounted on said lastmentioned shaft, the foregoing being but one unitpfwehich there may be aplurality,all in connection with the latter mentioned shatt, allsubstantially as set forth.

In witness whereof, I have hereunto subscribed my name in the presenceof two subscribing witnesses.
